Interactions between Intersecting Pedestrian and Vehicle Flows on Roads

The crossing of vehicle flow by pedestrians at either signalized crosswalks or locations away from crosswalks is studied using a car-following model. The model process is constructed, and two safe criterions deciding whether pedestrians begin to cross a road and a rule stopping vehicles at a signal intersection are proposed. Numerical results indicate that the relations of both vehicles' and pedestrians' delays to the width of pedestrian arrival interval are nonlinear; careful pedestrians unnecessarily spend more time to cross a road than aggressive ones; pedestrians crossing near a traffic signal have more influence on their and vehicles' delays. When pedestrians are permitted to cross a road using the gaps between slow vehicles, their delay may increase.
